(RESULTS) Patient research: NIH supported research is being conducted by the Rare Disease Clinical Research Network on the impact that the COVID pandemic is having on people living with rare diseases. You do NOT have to have been tested for COVID or have had symptoms of illness, the only criteria is to be under 90 years old and to have a rare disease. Caretakers or parents of children with rare diseases are also encouraged to participate.

COMPLETE WITH RESULTS: Clinical Trial: Dr. Satish Raj and the University of Calgary is recruiting POTS patients for a study of the effects of compression on the symptoms of POTS
***RECRUITING: DINET has partnered with PCORI (Patient-Centered Outcomes Research Institute), the University of Pittsburgh and the University of Pittsburgh Medical Center in the Story Booth project. Research is crucial to helping us further our understanding of POTS and other forms of dysautonomia and to identify ways to prevent or cure these conditions. That's why DINET is parterning with the Patient-Centered Outcomes Research Institute (PCORI) and the University of Pittsburgh on their MyPaTH Story Booth Project. The project aims to help researchers better understand the dysautonomia patient experience with illness, coping and the healthcare system. Researchers hope their findings will lead to the development of reserach studies that address topics that are important to patients and caregivers. Please visit our Story Booth page for more detailed information or to get started sharing your story. https://www.dinet.org/member-stories/story-booth-project-sharing-the-stories-of-patients-and-caregivers-r209/
CLOSED: (results pending) John Hopkins University is examining the use of a temporary celiac ganglion block before celiac ganglion resection in dysautonomia-related bowel dysmotility. Autonomic celiac ganglia resection has been shown to alleviate symptoms of dysautonomia-related dysmotility by interrupting the sympathetic stimulation to the GI system. Currently there has been no test to confirm this diagnosis pre-surgery. This studies objection is to temporarily block the ganglion to see if the symptoms go away, therefore confirming diagnosis and allowing for the more permanent surgical action. This study is recruiting patients with chronic dysmotility who are considering Celiac Ganglion resection. For further criteria and information about this study, please visit:

Recruiting: Vitamin D Deficiency in Dysautonomia In previous work the investigator identified a group of children between the ages of 10-18 years whose diagnostic workup for chronic nausea unexplained by conventional diagnostic tests has unexpectedly revealed underlying cardiovascular instability manifesting as orthostatic intolerance, primarily defined as postural orthostatic tachycardia syndrome (POTS) (88%). While this is an atypical initial presentation for orthostatic intolerance in general, the investigator believes that the cardiovascular problem is serious and represents a cause of nausea in a majority of these individuals, as treatment of the POTS with fludrocortisone reduced the symptoms of nausea. While fludrocortisone treatment abrogates the fall in baroreflex sensitivity (BRS) during tilt in part, it did not completely correct the tachycardia symptoms or the BRS suppression during HUT. Furthermore, it caused an elevation in MAP in a supine position, which may lead to future cardiovascular problems such as early onset hypertension and cardiac hypertrophy. This argues for a different treatment approach. The investigator presents preliminary data in this application revealing that OI subjects tend to have lower 25-hydroxyvitamin D (25(OH)D) compared to non OI subjects.
Open to children 10 - 18
Recruiting: A Study of Pyridostigmine in Postural Tachycardia Syndrome.
This is a 3-day study being conducted by the Mayo Clinic comparing pyridostigmine vs placebo in the treatment of POTS. Researchers expect pyridostigmine to improve tachycardia and stabilize blood pressure.
Eligibility: Diagnosis of Postural Tachycardia Syndrome using the following criteria:
Orthostatic heart rate increment greater than or equal to 30 beats per minute (BPM) within 5 minutes of head-up tilt.
Symptoms of orthostatic intolerance. These include weakness, lightheadedness blurred vision, nausea, palpitations, and difficulty with concentration and thinking.
Both criteria must be fulfilled

Recruiting: ME/CFS Activity Patterns and Autonomic Dysfunction The purpose of this study is to identify daily activity patterns, negative life events and autonomic abnormalities that may be related to non-improvement in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). For both naturalistic studies and behavioral intervention trials, roughly 50% of patients report worsening or unchanged illness. The proposed four-year study would be the first to look at the relationship between illness non-improvement, patient activities at home and autonomic function. Our long-range goal is to identify physiological signals and activity patterns that predict non-improvement and relapse and develop a self-management program that prescribes improvement-linked behaviors and discourages non-improvement activities.

Still Recruiting: Two new studies open for patients with MSA
The NYU Dysautonomia Center has 2 new clinical trials to test new drugs that are being developed for the treatment of OH in patients with MSA. Both compounds work by enhancing the body’s levels of norepinephrine. Both studies are also being carried out at the Autonomic Dysfunction Center at Vanderbilt University. NYU Dysautonomia Center and Vanderbilt are longtime collaborative partners in rare autonomic disorders.

Recruiting: The Big POTS Survey is still recruiting
This study’s lead investigator is Dr. Satish Raj MD MSCI, Adjunct Professor of Medicine at Vanderbilt University’s Autonomic Dysfunction Center. Dr. Rah says that the information collected as part of this survey “will help us learn more about the possible underlying causes and risk factors for developing POTS, treatments, and the economic, educational and social impact of POTS on patients and their families.” Dr. Raj serves on the Medical Advisory Board for DINET and Dysautonomia International. DI is sponsoring this survey.

(Completed, Results TBA) The Safety and Tolerability of Kinetin, in Patients with Familial Dysautonomia
The overall objective of this study is to assess the safety and tolerability of administering kinetin in patients with FD. The specific aim of this proposal is to determine the safety of a once-daily dose of kinetin in patients with FD using a dose ascending titration and to determine the long-term safety and tolerability during 3-years of receiving a maximum tolerated steady state dose of kinetin. The investigators hope to also demonstrate early proof of concept that kinetin enhances the ability of the neuronal tissue to correctly splice IKAP mRNA.
Eligibility: Male or female 16 years of age and older, confirmed a diagnosis of familial dysautonomia by genetic testing, written informed consent to participate in the trial and understanding that they can withdraw consent at any time without affecting their future care. And the ability to comply with the requirements of the study procedures.
